'service' and a general I To all whomrz't 'may concern. Be 1t known thatI, THOMAS CAMPFIELD, aV

citizen of the United States, residing at Unity, in the county ofyAlexander, State of Illinois, have invented certain new and usey fulImprovements in Portable Elevators;

andI do hereby declare the following to be a full, clear, yand exactdescription of the .in-

1 vention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to elevators, particularly to manually operatedelevators'for stores and similar places, and has for its object theprovision of a novel elevator which maybe moved `from place to place foruse and which isspecially adapted for the elevating of cakes of ice fromthe floor to the ice receiving door of the type of large refrigeratorsused in stores, Vbutcher shops, markets and other places. c

An important object of the invention is i the provision of an elevatorof this character which is `provided with means where# by it will beheld'iirmly upon the floor while in use so that it cannot shake or bedisplaced while cakes of ice dragged onto or off from it.

Arfurther object is the provision of a device of this character providedwith roller carrying members whereby it .may be readily draggedA fromplace to place, the roller carrying p members being capable of` beingswungso that the frameof the device will are being rest directly uponthe floor to insure its remaining stationary. n l

lStill another and more specific object is the provision of the deviceof this character having means engageable with the ceiling or a beam nsecured upon a refrigerator whereby the device may beadditionally heldagainst displacement. I 'i An additional object is the' provision r'of adevice of thischaracter which will be simpleY and efficient inoperation, durable 'in improvement of the art. Y

lVith theseand other objects `and advantages in view, the inventionconsists Yingthe rnovel construction, arrangement and combination ofparts as will be hereinafter more vfully describedfand claimed, andillustrated in the accompanying drawing, in which- Figure 1 isasideelevationl ofrmyidevice in positionready for use, Fig. 2 is asimilar view ofthe opposlte side, F 1g. 3 is -afront SpecificationV ofLetters Patent.

elevation,Fig. l is a cross sectional view on the line tf1 of F ig.V 1,Fig. is a top plan View', Fig. 6 .is n

through the lower portion of the device showing the roller carryingmembers swung so as to support the device upon the rollers, and Fig. lmodified means for holding the device stationary.` Referring moreparticularly to the drawing, the lnumeral 1() designates front uprightswhich are spaced from and parallel with similar rear uprights 11. Theuprightsl() and 11 are connected and supported at their upper ends bycross bars 12 and 13 which are suitably braced as shown.V

sition, the bottom 18 is disposed upon the cross bars 14 and 15 andalines with an inclined guidemember 20 hinged upon the forward cross bar15 as shown at 21.

In order that the elevator member may be raised and lowered, I provide amandrel 22 journaled .in brackets 23 secured upon the forward uprights10 and provided upon its end with a gear 241. A cable 25 has one endsecured to the mandrel 23 and extends upwardly and over a pair ofrollers 26 journaled in bars 27 secured across the top cross bars 12,and has its other end secured to the top 17 of the elevator member asshown at 28. A shaft 29 is journaled on the bracket 23 and is providedupon one-end with an operating handle 30 and has secured thereon a.pinion 31 meshing with the gear 24. It will be seen that when the shaft29 is rotated by the handle 30 the mandrel 22 will be turned and theelevator member raised within the frame` formed by the uprights.

In order that the elevator membeiniay be held at any desired position, Ipreferably provide nieansr for locking the mandrel againstrotation,which means may conveniently be a ratchet 32 secured upon the shaft 29and engageable by a pivoted pawl 33 upon the adjacent upright 10.

i VIn order that my device may be ported conveniently from place toplace, I

provide members 34 hinged, as at 35, `upon the cross bars 14 at thebottom of theframe@ 1 adjacent the free be disposed vertically beneath`the cross barsl4.V i y When it isjdesir'ed to adapt my device'for use,so that the rollers 36 will not engage through `bearings the -floor, themembers are' Vswung -upwardly and outwardly assho'wn 1n Figs. l,

3S secured upon the cross bars I4.' The `rod -37iis provided at one endwith an'operating lever 39 by ',whichit may be rocked. Crank arms therod 37 and have theirhorizontal portions 441 extending through rings/42'pivot-v allyvsecured upon the members 34. The de vice being in theposition shown in Fig.l 6,

with the rollers 36 engaging the floor', rock-i 39 to either side willcause the ing the lever cranks to move upwardly, 'thereby swinging themembers 34 upwardly and al-4 lowing the lowerends 'of the uprights 10.vand llto rest upon the door.

The use of my device isas follows. r V*After Y the device hasbeen'mov'ed, as byfdragging elevator and into it upon its rollers to theice box" or other place are swungiupwa'rdly, as described, s o that thedevice will rest with its uprights engag-V ing the floor. The elevatormember being in its lowest position, cakes oii'ice or the like arevslidup the guide member 20'and on to the bottom' 18 of the elevator. p byturning the handle 30, the cable 25 will be wound upon the mandrel 22and the elevator member will be raised to the 'desired position. lThecakes of ice :or the like may then be the refrigerator or other placewhere they are desired. i

In'order that the device may' be held rigidly. in place and preventedlfromlwabblingor shaking I provide avertically eX- tending bar 43slidablewithin guides 44 secured Vuponoross 'bars 45 connecting two ofthe sideuprights. Thebar 43 may be slid upwardly intoa slot 46 formed inaV member 4 Y `of the room or building in which the device is usedsk Apin or boltf48 may thenfbe in-` serted within the proper one of aseriesof apertures 49 formed in the bar 43.*so that itV Vwill engage the topface of thelowermost guidel 44L for preventing the rod 43' from slippingout of the slot 46.7' The bar "43 is prevented from slipping- 44 by alug 50.-.
